Charged particle beams, specifically relativistic electron beams, offer unique advantages. Electrons can be accelerated to nearly the speed of light with relatively little energy compared to ...

The Relativistic Heavy Ion Collider, a U.S. Department of Energy (DOE) Office of Science user facility for nuclear physics research at DOE’s Brookhaven National Laboratory, entered its 25th and final ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy.

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged.

While relativistic effects are well-understood ... The tunability is based on the mechanism known as mass-energy equivalence (from Einstein's famous equation E=mc²), which means that changes ...

But now we need to tackle the rest of relativity: How do we arrange matter and energy to make ... The universe has been expanding ever since the Big Bang almost 14 billion years ago, and ...
